information

The RTSP Server object is used for transmitting video from Server server to remote workplaces workstations using the RTSP protocol. Use The use of the RTSP protocol allows viewing you to view video from IP cameras and video archive on remote Clients clients by means of Axxon PSIM or using use video players that support this protocol. Transmitting Transmission of the archive of the Videogate and Backup archive is the videogate and backup archive is also supported.

If there is a live video with audio or the archive is recorded with audio, then video transmission with audio through RTSP Serverserver is supported—for this specify the ID of microphone from which the archive is recorded when requesting video (see the table with requests examples at the foot of the page Examples of addresses to view video from RTSP Server). For the audio to play correctly in VLC Media Player, set the VLC media player compatibility mode checkbox (see below).

Note that when configuring, each RTSP Server each RTSP server loads only one CPU core. To increase the number of rtsp streams, you must create several RTSP Server objects and configure them on several cameras. Each RTSP Server server entity runs in a separate system process (StreamingServer.run).

object

Create To create the RTSP Server object as follows object, do the following:

1. In the context menu of the Computer object, select Create object → RTSP Server.
2. Specify In the settings panel that opens, specify the name and ID of the object in the settings panel that opens.
   Image Modified
   
3. Click the Apply button to create the object.

...

Configuration of the Unicast mode

1. Open Go to the settings panel for of the RTSP Server object. For this select the created object in the Axxon PSIM objects tree.
   

2. In the Cameras table, set the checkboxes next to video cameras, video from which is to be displayed (1)you want to display. If a camera has several streams, the default stream is broadcastedtransmitted.

   Info
   title Note
   If the default stream is changed on the settings panel of the corresponding corresponding Camera object settings panel after applying you apply RTSP Server server settings, it is mandatory to you must click the Apply button on the the settings panel of the RTSP Server object settings panel to apply changes to it as well. See also Configuration of also Configuring the multistream video.

3. If video from the camera must be received through the videogate, then select the Videogate object from the Gate drop-down list (2).
4. If archive from the camera must be received from the backup archive, then select the Backup archive object from the Backup archive drop drop-down list (3).
5. Set the Unicast checkbox if signals from all cameras must be broadcast through one port (4).
   

6. In the RTSP port field, specify the port via which the video is transmitted (5).

   Info
   title Note
   The "Windows Media Player Network Sharing" service can use the default port 554. To enable broadcasting, you must change the port or disable this service. To disable the service, go to the Control panel → Administrative Tools → Services and double-click the service name and click the Stop button in the window that opens.

7. In the HTTP port field, specify the port for transmitting video via http HTTP protocol (6).

...

Configuration of the Multicast mode

Features of the Multicast mode:

1. To get a multicast video in Axxon PSIM (see Configuring Receive multimedia receipt using stream via RTSP protocol), set the multicast value to the RTSP parameter in the HKEY_LOCAL_MACHINE \SOFTWARE\AxxonSoft\PSIM\Video\TransportProtocols registry section (for 64a 32-bit system the path is HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\AxxonSoft\PSIM\Video\TransportProtocols) on computer where the the Camera object is created. For detailed information on this parameter, see Changing see Change the transport protocol used by IP - device.
2. RTSP Serverserver can broadcast simultaneously in Multicast and Unicast modes. Receiving both such streams on the Axxon PSIM client is impossible due to RTSP key, which determines the connection mode (see above). However, the VLC player allows receiving streams in both modes in at the same time.
3. The ports that are assigned to each camera in this mode will not be aren't displayed in the Windows OS Resource Monitor and other similar operating system resource monitors.

Using the Multicast mode allows you to reduce the load on the Server server by reducing the amount of transmitted data. To distribute the transmitted signal among different RTSP ports, do the following:

1. Go to the settings panel of the RTSP Server object settings panel.

2. Set the Multicast checkbox (1). The Port column is displayed in the Cameras table.

3. Specify a data transmission port for each video camera in the Port field (2). Bear in mind the following when specifying ports. When you specify ports, note the following:

   1. The following ports are in use used for each camera in the Multicast mode: nPort, nPort + 18000 (rtp), nPort + 19000 (rtcp), where nPort—port nPort is a port number specified for camera in the the Port column.
      For proper the correct operation of RTSP server in the Multicast mode, these ports are to must be vacantfree.
   2. Specified ports are not addressed directly. Use RTSP port to get video from all cameras in the Multicast mode (see step 5).

   3. In spite of specifying Even if you specify video data port, it is required to you still must specify camera number in the data source address (see the table below Examples of addresses to view video from RTSP Server).
      

4. In the Receiver IP address field (3), specify the address from which the broadcast in the Multicast mode will be performed. Address must be in the range from 224.0.1.0 to 239.255.255.255. By default, the receiver IP is 224239.01.1.150. Bear in mind the following when specifying Receiver IP address:When you specify the receiver IP address, note the following:

   1. The address range from 224.0.0.0 -to 224.0.0.255 address range is reserved for routing protocols and other service protocols. Destination IP address You cannot be set Receiver IP address from the specified range.

   2. RTSP - server can broadcast only to one network simultaneously. The network with minimal metric is selected by default. To change the broadcast network, go to the the Advanced settings tab (see below).

   3. Set different Receiver IP address and RTSP port if several RTSP Servers are in Multicast modeWhen you configure several RTSP Servers in the Multicast mode, you must specify different values for them in the Receiver IP address and RTSP port fields.
5. In the RTSP port field (4), specify the number of port through which video signal will be sent in the Multicast mode. When requesting video data from the camera using the RTSP protocol, it is necessary to specify this port. The system itself forwards the request to the port of the requested camera.

Advanced settings

To specify the advanced settings of RTSP Serverserver, do the following:

1. Go to the Advanced settings tab.
   

2. If the current time must be sent to VLC Media Player instead of the frame time, then set the VLC player compatibility mode checkbox (1). This option can be used in case of problems when . You can use this option when there are problems with playing back the archive received over RTSP in VLC Media Player.

3. If RTSP Server server is used to broadcast video data to the ECHD system, then for the correct operation of navigation through the archive, set the the ECHD compatibility mode checkbox (2).

4. If there are captions on the video (see Configuring captions display output on a video image), set the Use captions track checkbox (3) to checkbox to send them together with video via RTSP Server and to display them in the receiving app—VLC player.
   Also, when this checkbox is set, time captions are added to the video image in the format YYYYMMDDTHHMMSSZYYYYMMDDTHHMMSSZ.If the video is archive archived (see request examples below Examples of addresses to view video from RTSP Server), then the captions show the archive time. However, if the VLC player compatibility mode checkbox is set together with the Use captions track checkbox, the time in the captions is current.

   Note
   title Attention!
   Correct video playback and captions operation are guaranteed in VLC Media Player version 2.0.0. These features are not guaranteed to work in other versions of VLC Media Player or other programs.

5. If you want to eliminate a delay of several seconds when requesting a video via RTSP, set the Hot connection mode checkbox (4).
   

   Info
   title Note
   The delay when requesting a video via RTSP can also depend on the camera key frame rate (FPS) settings or the frame buffer size settings in the player.

6. From the Source IP interface drop-down list, select the name of the network interface that must be used to broadcast the RTSP server (5).

7. If the RTSP Serverserver is used for broadcasting the video data to the ECHD system, and the Video Surveillance Servers the servers of the surveillance system are behind NAT, then it is necessary to specify the NAT settings:

   1. In the IP address field, specify the IP address of the router that performs the NAT broadcasting (6).

   2. In the Port field, specify the port of the router, which is accessed by the client when executing the ECHD requests (7).

      Info
      title Note
      To enable the substitution of the router's specified IP address and port to the ECHD requests, it is necessary to set the corresponding checkbox in on the settings panel of the Web server object—see -Server object—see Enabling the processing of ECHD requests and selecting rtsp server.RTSP server.

8. In the Number of threads (min/) field, specify the value that corresponds to the initial number of threads that are created when the RTSP server is started. The default value is 1.
9. In the Number of connections per thread field, specify the value that corresponds to the maximum number of client connections per thread, with equal distribution. If this parameter is exceeded, a new thread is created. The default value is 20.
10. In the Number of threads (/max) field, specify the value that corresponds to the maximum allowed number of threads that can be created. If there are too many threads, server rejects additional connections. The default value is 100. 

11. Click the Click the Apply button to save the changessettings.
